Air Canada interview questions

Very slow process, took over a month from applying through to the final piece of the process before a potential offer of employment. The role is primarily communicating with customers via email, ironically AC’s email communication was mediocre. The final step was to complete a Comprehension Test via Teams, however none of the links given in that email worked, and I was unable to access the meeting by manually entering the information. There were no contact numbers to call, and no direct email to someone who I could advise that the links were not working. I missed the opportunity to take the assessment. I emailed the general address used to send the invite, to no response. I emailed a company address of another recruiter I had been contacted by much earlier in the process, also to no response. Other than the issues in the final step to which they give no opportunity for resolution, the process was ok, just very lengthy.
